FN 5.7 x 28

The 5.7 x 28 round was developed in the 1980’s by Fabrique Nationale Herstal (FN) of Belgium.

FN 5.7 x 28 is a rifle caliber round, but shortened to be small enough to be used in pistols. This gives weapons in thr 5.7 x 28 caliber enormous magazine capacities. The FN P90 rifle has a standard magazine capacity of 50 rounds, while the FN Five-seveN pistol features a magazine capacity of 20 rounds.
